Although a growing body of literature points to the particular media diet of populist voters, we know too little about what specific media preferences characterize citizens with populist attitudes. This article investigates to what extent citizens with antiestablishment and exclusionist populist attitudes are attracted to attitudinal-congruent media content. We collected survey data using a nationally representative sample (N = 809) and found that citizens’ preferences for media content are in sync with their populist attitudes. Beyond having a tabloidized and entertainment-based media diet, populist voters self-select media content that actively articulates the divide between the “innocent” people and “culprit” others. These findings provide new insights into the appeal of different types of media populism among citizens with populist attitudes on different dimensions. 相似文献

Although much attention has been paid to how media use and interpersonal discussion motivate people to engage in political persuasion, and despite recent efforts to study the role of digital media technologies, less is known about the creation of news and public affairs content online. This study sheds light on how online content creation works alongside other communicative behaviors, such as news use and political discussion, to affect attempted political persuasion. Using two-wave panel survey data, we find that political discussion and citizen news creation mediate the relationships between online and traditional news use, on one hand, and attempted persuasion, on the other. Furthermore, strength of partisanship moderates the relationship between content creation and attempted persuasion. Findings are discussed in light of their implications for the political communication and public sphere processes. 相似文献

Despite the proliferation of research on social media and journalism, only a few studies have analyzed how journalists in Latin America embrace the affordances of social platforms for journalism practice. Based on a survey of 877 Latin American reporters, this article examines the platforms journalists use and how they use them. The broad finding is that, despite the great popularity of Facebook in the region, Twitter is the most important platform for daily newsgathering and journalistic work. Journalists turn to Twitter to find sources and stories, showing an important openness to participatory journalism. Yet, they mistrust information provided from political sources. Our findings show that different regions in Latin America work with social media in different ways, and local journalistic cultures have an impact on these adoptions, especially in the case of Brazil. Further research and implications for the field are discussed. 相似文献

This article seeks to explain political persuasion in relation to second screening—people’s use of a second screen (i.e., smartphone/laptop) while watching television to access further information or discuss TV programs. Employing a two-wave-panel survey in the United States, results show this emergent practice makes people more open to changing their political opinions, particularly among those who habitually use social media for news or frequently interact with others in social media contexts. 相似文献

Collaborative filtering is concerned with making recommendations about items to users. Most formulations of the problem are
specifically designed for predicting user ratings, assuming past data of explicit user ratings is available. However, in practice
we may only have implicit evidence of user preference; and furthermore, a better view of the task is of generating a top-N
list of items that the user is most likely to like. In this regard, we argue that collaborative filtering can be directly
cast as a relevance ranking problem. We begin with the classic Probability Ranking Principle of information retrieval, proposing a probabilistic
item ranking framework. In the framework, we derive two different ranking models, showing that despite their common origin,
different factorizations reflect two distinctive ways to approach item ranking. For the model estimations, we limit our discussions
to implicit user preference data, and adopt an approximation method introduced in the classic text retrieval model (i.e. the
Okapi BM25 formula) to effectively decouple frequency counts and presence/absence counts in the preference data. Furthermore,
we extend the basic formula by proposing the Bayesian inference to estimate the probability of relevance (and non-relevance),
which largely alleviates the data sparsity problem. Apart from a theoretical contribution, our experiments on real data sets
demonstrate that the proposed methods perform significantly better than other strong baselines.

In recent years the loss of effectiveness of television advertising based on traditional spots has led to the development and consolidation of new forms of advertising. In this article, the authors analyze the recall effectiveness of three new television advertising formats (television billboards, internal telepromotions, and external telepromotions). We use a representative sample of Spanish television audiences to compare the advertising recall generated by each new form of advertising. The empirical analysis, carried out by means of a probit model, shows that television billboards generate better recall than external or internal telepromotions. 相似文献

In 1993 a new comprehensive curriculum for secondary education was introduced in the Netherlands. In that curriculum learning objectives related to environmental education are formulated. This paper describes: (1) the present situation regarding EE in schools in the northern part of the Netherlands on the subject level, as regards the relative importance attributed by teachers to the different objectives of environmental education. (2) the constraints and the need for support when teachers want to pay more attention to the various objectives of environmental education. Teachers pay most attention to the objectives of EE that are aimed at improving the knowledge of the relationship between man and the environment and the environmental problems and their causes. They seem to underestimate the objectives aimed at skills and attitudes. Teachers show only a slight tendency to change their current practice towards more environmental education. The main reasons are described. A considerable number of teachers are willing to use support to implement environmental education if that is offered, but more than half have made no decision yet. The kind of support wanted by teachers differs with different objectives. The paper concludes with a discussion of the prerequisites of a supporting programme for the implementation of environmental education. 相似文献

To refine selective admission models, we investigate which measure of prior achievement has the best predictive validity for academic success in university. We compare the predictive validity of three core high school subjects to the predictive validity of high school grade point average (GPA) for academic achievement in a liberal arts university programme. Predictive validity is compared between the Dutch pre-university (VWO) and the International Baccalaureate (IB) diploma. Moreover, we study how final GPA is predicted by prior achievement after students complete their first year. Path models were separately run for VWO (n = 314) and IB (n = 113) graduates. For VWO graduates, high school GPA explained more variance than core subject grades in first-year GPA and final GPA. For IB graduates, we found the opposite. Subsequent path models showed that after students’ completion of the first year, final GPA is best predicted by a combination of first-year GPA and high school GPA. Based on our small-scale results, we cautiously challenge the use of high school GPA as the norm for measuring prior achievement. Which measure of prior achievement best predicts academic success in university may depend on the diploma students enter with. 相似文献

New public management and increasing levels of competition driven by global rankings are bringing the managerial practices of public and private higher education institutions closer together. However, these two types of institutions still maintain different objectives and traditions and enjoy different degrees of autonomy that are reflected in their internal organisational structures. We study the relative efficiency and productivity performance of private and public universities in Spain through two adaptations of the Malmquist Index. Results show that, in 2009/2010, the greater flexibility of private universities meant a better adjustment between inputs and outputs in the private sector. However, in 2013/2014, public universities had caught up with private universities. Because of the economic crisis, the inputs of public universities have decreased, but this decrease had not fully impacted their results in 2013/2014. 相似文献
